.l M PROVEMENT IN STREET-CARS.

Specification forming part of Letters Patent No. 215,198,, dated May 6,1879; application filed October 3, 1878.

To all whom it mag concern Be it known that we, ROBERT HARDIE and JOHNJAMES, both of the city and State of New York, have invented certain newand useful Improvements in Cars Propelled by Air or Gas under Pressure,of which the followingis a description, reference being had to theaccompanying drawings, forming part of this specification.

This invention more particularly relates to compressed-air cars forstreet-railroads; and consists in certain combinations of reservoirswith a metallic framing of novel construction, whereby great strength iscombined with lightness, and the same framing which supports thereservoirs also supports the engines by which the car is propelled.

In the accompanyingdrawings, Figure 1 represents a horizontal section onthe line 00 at in Fig. 2 of a compressed-air car, showing the largerportion of the flooring removed and hav- "ing our invention applied.Fig. 2 is a vertical longitudinal section of the same on the irregularline 3 y in Fig. 1. Fig. 3 is a transverse vertical section on the linew w in Fig. 2, and Fig. at is a further transverse vertical section onthe line 2 2. Fig. 5 is a side elevation, mainly of a lower metallicframing and reservoirs, with the wood-work of the car removed.

A, B, and O are compressed-air reservoirs, arranged side by side atopposite ends of the car and beneath the floor R of the body S thereof.These reservoirs extend beyond the ends of the car-body and beneath theopposite end platforms, D, of the car, but are of such restricteddimensions in their length as to leave a sufficient space between bothend series for the engine or engines and driving mechanism of the car,Said reservoirs are of cylindrical construction, and one of them, 0, onopposite sides of the car, at opposite ends thereof, is shorter than therest to provide for the arrangement of the side steps, E, to theplatform.

When steps are required on both sides of the opposite ends of the car,then the reservoirs A are similarly shortened.

G G are opposite side girders, forming part of a lower metallic framing,and arranged between the opposite end reservoirs, A O A 0. These girdersare composed of upper and lower angular or L-shaped members, I) c, and aconnecting web-plate, d, and connect with and are secured to oppositeend frames, H, at the inner heads of each series of reservoirs A B O,and also by an extension of the upper members, b, to the opposite endplatforms or platform-bases, D, of the car.

The several reservoirs A B G are riveted, bolted, or otherwise securedto the end frames, H, and platform-bases D, formed of metallic plates,whereby the girders G not only serve to unite both series of oppositeend reservoirs, A B 0, but to support them and keep them from sagging attheir outer ends, and said reservoirs form parts of a supporting-basefor the floor of the car, and the girders Gother parts thereof. Saidgirders are tied togetherintermediately of their length by aplate-brace, I, which combines with the girders and end frames, H, toconstitute a lower metallic framing, that not only supports thereservoirs A B 0, but also forms the framing fbr the engine J of thecar, the cylinders of which are secured to the side girders. Theaxle-boxes f of the car and springs g controlling the same are or may bealso carried by the girders.

Outside of the girders G and parallel with them are upper and lowerlongitudinal ties or braces, h 5, arranged to connect the opposite endheads or frames, H, and between the longitudinal braces h and thegirders G are secured diagonal braces K K, which serve to stiffen thegirders laterally. These longitudinal and diagonal braces also form partof the lower metallic framing, of which the gird ers are a prominentelement. Said lowermetallic framing'combines lightness with greatstrength, and not only serves to carry the res ervoirs and to supportthem against deflection and from lateral disturbance, but also forms afirm base for the car-body, as well as being the framing of the engine.Such framing likewise serves, by means of saddles Icon the end frames,H, to support or carry additional upper compressed'air reservoirs, M M,arranged to extend throughout the length of the car beneath its seats.These reservoirs and the several braces K K, secured between the bracesh and the girders G, and serving to stiffen the girders laterally, allsubstantially as shown, and for the purposes described.
